JACOB HIMMES, OF CHICAGO, ILLINOIS.

PLATFORM-SCALE.

To all whom it may concern: 7

Be it known that I, JACOB HIMMEs, citizen of the United States, residingat Chicago, in the county of Cook and State of Illinois, have inventedcertain new and useful Improvements in Platform-Scales; and I do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

This invention relates to a novel construe tion in a scale platformparticularly adapt ed for large scales such as are used for weighingloaded wagons and railroad cars, the object being to provide meanswhereby the upper or super-structure of the platform will be renderedcapable of limited movement relatively to the bearing feet supportingthe same, and consists in the features of construction and combinationsof parts hereinafter fully described and claimed.

In the accompanying drawings illustrating this invention Figure -1 is aview in side elevation partly in section on the line 11 of Fig. 2- ofthe platform portion of a scale showing the main levers, the bear ingfeet supported thereon and the scale platform supported upon saidbearing feet. Fig. --2 is a detail transverse section on the line 2- -2of Fig. 1. Fig. -8 is a detail plan view showing one of said bearingfeet.

The object of my invention is to provide means whereby relative movementof the scale platform and bearing feet is permitted so as to relieve thescale pivots from the strains ordinarily imposed thereon and maintainthe same constantly in proper position to maintain the accuracy of thescale.

The scale platform which is here represented by beams A upon whichflooring or the like, indicated at B, is mounted and upon which rails Care supported, is mounted upon the bearing feet D of the scale; thelatter being supported in the usual manner upon the scale pivots Ecarried by the main levers F in the usual manner. The said bear ing feetD are provided at their ends with flanges G and H, the latter beingprovided with substantially triangular openings I through which the endportions of rollers P project. Supported upon the upper endsSpecification of Letters Patent.

of said flanges H and G are pins K upon which the links L are supported,the latter receiving the said end portions of said roller P in theirlower ends; said rollers being thus suspended from said pins K. Saidlinks L are held against movement longitudinally of said pins K by meansof cap plates M mounted upon the said upper ends of said flanges G and Hin any welLknown manner. The said end portions of said rollers P areannularly grooved as at N to receive the said links L to prevent theescape of said rollers therefrom and to maintain said rollers normallyout of contact at their ends with the inner faces of said flanges G. Thebeams A are provided on their lower faces with plates 0 provided betweentheir ends with concave recesses J in which said rollers P are received,said recesses J being of greater radius than said rollers so as topermit the latter to move therein to a limited extent. The said platformAB is thus suspended by means of the links L and rollers P from ,saidpins K and by reason of the triangular openings in the flanges H and thefree spaces between the ends of said rollers J and the inner walls ofthe flanges G said platform A-B is capable of limited movementlongitudinally and laterally relatively to the bearing feet D withoutaffecting the pivots E, as will be obvious.

I claim as my invention:

1. In scales of the kind specified, the combination with the bearingfeet, of rollers supporting said platform, and links carrying saidrollers suspended from said bearing feet.

2. In scales of the kind specified, the combination with the bearingfeet, of rollers supporting said platform, pins on said bearing feet,and links suspended from said pms and carrying said rollers.

3. In scales of the kind specified, the combination with the bearingfeet, and the scale platform, of end flanges on said bearing feet, pinssupported on the upper ends of said flanges, links depending from saidpins, and rollers hung in said links, said platform resting on said.rollers.

4. In scales of the kind specified, the combination with the bearingfeet, and the scale platform, of end flanges on said bearing feet,flanges parallel therewith and disposed inwardly thereof pins spanningthe upper name in presence of two subscribing witends of said flanges,links depending irom nesses. said plns between said flanges, and rollerspassing at their ends through openings in the JACOB HIMMES' innerflanges hung in said links said platfitn g g; form resting on saidrollers. RUDOLPH M, LoTz In testimony whereof I have signed my 5 H. M.BOYLE.
